1.The Chemical Composition of Traditional Chinese Medicines＇ substance Chinese medicine and tially a special, macrocosm its compound is essen- drug group , which was made of a different chemical composition of the Chemical mother nucleus. Chinese medicine effec- tive components such as alkaloids, flavonoids, glyco- sides, etc., which molecular weight is less than mostly. They constitute the material basis of the Chi- nese medicines. On the other hand, non-medicinal ingredients such as starch, proteins, pectin, tannin ＇s molecular weight islarge than 50,000. It is be- lieved that they are the main cause of the current Chinese medicine＇ s disadvantagessuch as large taking dose, poor stability andpoor quality control system, therefore, it requires the ＂refine ＂unit opera- tions to remove the non-medicinal ingredients.
